Solving a Program
In chapter 7 you saw how you can enter an equation — it's added to the
equation list — and then solve it for any variable. You can also, enter a
program that calculates a function, and then solve it for any variable. This is
especially useful if the equation you're solving changes for certain conditions
or if it requires repeated calculations.
To solve a programmed function:
1. Enter a program that defines the function. (See "To write a program for
SOLVE" below.)
2. Select the program to solve: press
{ V
label. (You can skip this step
if you're re–solving the same program.)
3. Solve for the unknown variable: press
{ 
variable.
Notice that FN= is required if you're solving a programmed function, but not
if you're solving an equation from the equation list.
To halt a calculation, press

or
f
. The current best estimate of the root
is in the unknown variable; use
{ 
to view it without disturbing the
stack. To resume the calculation, press
f
.
To write a program for SOLVE:
The program can use equations and RPN operations — in whatever
combination is most convenient.
1. Begin the program with a label. This label identifies the function shat you
want SOLVE to evaluate (
/
label).
